[英]Insert data to database - LARAVEL
這為我創建了一個新項目。 但是,我想要做的是在數據庫中添加屬於另一個名為 projects_air 的數據庫表的附加字段,並為該項目添加這些空氣詳細信息。
public function newProject(Request $request)
{
$data = $request->all();
$attributes = [];
$attributes['title'] = $data['title'];
$attributes['start_date'] = date("Y-m-d h:i:s", strtotime($data['start_date']));
$attributes['end_date'] = date("Y-m-d h:i:s", strtotime($data['end_date']));
$attributes['created_by'] = Auth::user()->id;
$attributes['description'] = $data['description'];
$attributes['air'] = '10';
$attributes['water'] = '19';
$attributes['lat'] = $data['lat'];
$attributes['lng'] = $data['lng'];
// var_dump($attributes);
// return;
$project = Projects::create($attributes);
$air = Projects_air::create($airattributes);
if($project)
return redirect('home')->with('success', 'Project added successfully');
var_dump($data);
return;
}
要插入數據庫的其他數據:
$airattributes['dust'] = $data['dust'];
$airattributes['noise'] = $data['noise'];
$airattributes['temperature'] = $data['temperature'];
$airattributes['radiation'] = $data['radiation'];
我希望這些數據也屬於一個項目,它們(projects 表和 projects_air 表)都有一個名為“project_id”的列
我試過使用這個$air = $project->air()->create($airattributes);
project- $air = $project->air()->create($airattributes);
但我收到一個錯誤,即 COLUMN PROJECTS_ID 不存在,這是真的。 它應該是 PROJECT_ID 但我不知道錯誤在哪里
這里可以查看界面: http : //188.166.166.143/projects/add
更新:空氣模型:
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Air extends Model
{
protected $table = 'projects_air';
/**
* The attributes that are mass assignable.
*
* @var array
*/
protected $fillable = [
'project_id', 'temperature', 'radiation', 'dust', 'noise'
];
/**
* The attributes that should be hidden for arrays.
*
* @var array
*/
protected $hidden = [
'id',
];
}

定義模型中的關系:
class Projects extends Model {
public function air() {
return $this->hasMany('App\Projects_air');
}
}
然后在您的控制器中:
$project = Projects::create($attributes);
$air = $project->air()->create($airattributes);
